University of Michigan researchers have discovered that oxidative stress experienced early in life increases subsequent stress resistance later in life. Oxidative stress happens when cells produce more oxidants and free radicals than they can deal with. It’s part of the aging process, but can also arise from stressful conditions such as exercise and calorie restriction.
Examining a type of roundworm called C. elegans, U-M scientists Ursula Jakob and Daphne Bazopoulou found that worms that produced more oxidants during development lived longer than worms that produced fewer oxidants. Their results are published in the journal Nature.
